So should i buy 2 now, please explain what the unibody is that you're talking about idk too much bout macs.

Here's another stat of my mac:

Sorry I answered you wrong, the new unibody MBP batteries can be changed, you can do it yourself, BUT IT WILL VOID WARRANTY..

basically the new unibody ones dont have the latches that us older owners have, if you look in the bottom of you MBP 2 latches you can open and you can switch batteries and other components easy w/o voiding the warranty, but in the new unibody ones, ones you open that case, all warranty goes down the drain, unless you go to an official apple store.

If it was up to me, I would buy 2 or even 3 just to be sure.. but then its up to you.

lemme know how much it costs for all batteries replaced & installed for you.

like I said above in the older versions of MBP you can change the batteries yourself w/o having to go to an apple store, plug and play..

I opened up my MB unibody just fine without voiding the warranty. You just can't mess with any stickers. I only have 12 cycles on it and I'm going to get a new one around 250-500. It's not expensive or anything. Easy install. Just do it your self.

Well then isn't getting Unibody better, newer, graphics, performance plus it dies after 1000 cycles, but you're saying i need a new one and i just am at 336 cycles.
